Application September 16, 1949, Serial No. 116,019

s Claims. (o1. 4-1s7) l This invention relates to pads and particularly pertains to anew and useful sink pad adapted to prevent damage to both dishwa're and sinks. The dropping of dishware in a sink during the washing thereof or the handling thereof above a sink, as in the stacking of dishes in a cabinet above a sink, is not an uncommon accident and, due to the hardness of the materials with which 'sinks are manufactured, results almost invariably in the shattering of the dropped pieces. Often the mereplacing of finer glassware in a sink is suicient to cause chipping or the complete breakage thereof.

Also, in the cleansing of pots the use of a scouring powder is in wide practice. Included in the composition of most of said scouring powders can be found pumice or other abrasive ingredients. In time these abrasives cause the wearing away of the enamel, porcelain, or other material with which a sink may be coated. Thus there is effected a darkunsightly spot in .the sink, and, as in the case of a porcelain coated metallic sink, this wearing away of the surface coating may be sucient to permit the corrosion of the metal thereunder. Y

Also, the amount of grease and the like which can be accumulated on a sinks bottom during a single daycan be considerable, as can be the amount of labor required to remove that grease from said sink bottom.

Therefore, one object of the present invention is to provide means whereby the breakage of dishware and glassware may be decreased considerably. e

Another-object of the present invention Vis to provide means whereby the bottom of a sink may be cushioned or padded to thus decrease dishware and glassware breakage resulting from the accidentaldropping or placing thereof into a sink.

Another object of the present invention is to provide means whereby a sink bottom may be cushioned or padded without the effect of stopping-up the sink drain.

- Another object of the presentinvention is to provide drainage means in a sink bottom cushion orpad, to' thereby eleminate the possibility of accumulatingwater on the surface of the cushion.

Another Iobject of the present invention is to provide meansr whereby a sink bottom may be protected from discoloration and corrosion due to cleansing abrasives.

Another object of the present invention is to eliminate the accumulation of grease andthe like on a sink qriottc'm. Y

Still anotherf object of ythe present invention is l'iV d to provide a. sink bottom cushion which is adaptable for utilization as a drainboard pad.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

, In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is an isometric View illustrating one embodiment of the present invention.

Fig. 2 is a sectional view taken along the lines 2-2 of Fig. 1; thus facilitating the understanding of the construction of the irst embodiment.

Fig. 3 is a sectional view of a sink, illustrating the contemplated employments of the present in- The sink pad, according to the rst form of the invention shown in Figs. 1 to 3, includes a pad body I0 formed, preferably by moulding, of

-rubber, plastic or any similar iiexible material and comprises a base Il of rectangular or any other configuration which might conform more readily with a sink bottom. As better seen in Fig. 2, a vertically extending rib I2, formed duringthe moulding process, is provided marginally on three sides of the said base ll.

` l I of any suitable soft material.

' rNow as seen in Fig. 3, the pad I0, when positioned in a sink l5 completely protects the bottom thereof, and, in view of the resiliency of rubber and the like incomparison with the hardness of the sink itself, aiords a decidedly softer surface for dishes or glassware which might be placed or accidentally dropped into the said sink.

,The afore-mentioned aperture i4 is so disosed lin the base Il as to register with sink rain I6 which permits unhampered drainage of cally extending rib 33.

the sink and also prevents the shifting of the pad Ill incidental to the seepage of water thereunder. Inasmuch as the marginal rib I2 exists only on three sides of the base II, drainage of the surface of the pad I is facilitated, thereby eliminating the nee'd for raising the pad after each running of the water to prevent the accumulation of water on the surface thereof. When utilized with a sink having a drainboard I1, the pad ID, is equally useful thereon for the protection of dishware prior to the drying thereof. Here, too, it may be seen that the surface y of the pad IIl will be always inclined to drain itassures proper drainage of the sink, which is also aided by convexities 31 formed on the under-side of the under-sheet 34 for permitting a flow of water beneath the pad and to said sink drain. The mentioned marginal ribs 33 on the three sides of the base 30 permit a drainage of water oif the surface, in the manner above mentioned with regard to the other embodiments.

Whereas, in the second described embodiment the sponge rubber was in sheetform and provided a cushion to dishware dropped anywhere on the pad I0, it will be understood that the present embodiment, though employing only cylinders 36 of sponge rubber, provides Aan equal The second embodiment of the pad body IU, K

seen in Figs. 4 and 5, provide for a quadrilateral base member 20, also of rubber, a plastic, or suitable like material, and is so formed to provide marginal and vertically extending sides 2 I. Said sides are provided internally with a groove 22, which groove is adapted to receive therein the edges of Va top sheet 23 of similar material and configuration, and also having the longitudinal ribs I3 formed thereon. The edges of said top sheet 23 are sealed in the said groove 22 by a heating process, cementing, or other suitable means. Prior to said sealing, however, a sheet of cushioning material 24, such as sponge rubber or the like, is interposed between the said base member and the top sheet 23. In the present embodiment a drain hole 25. comprises axially aligned holes in the base 20, the cushion sheet 2.4, and the top sheet 23, and Water is prevented from seeping therebetween by a rubber sleeve 26 secured in place by the heretofore mentioned heating or cementing sealing process. This arrangement provides an even more soft cushion for dishware accidentally dropped into a sink and is employable in the same manner as the first embodiment hereinabove described.

Another embodiment is seen in Figs. 6 and '7, wherein a rectangular rubber or plastic base member 30 is provided and has formed thereon downwardly extending sides 3l, which sides have internally therein a groove 32. On the upper side of said base member 30 and on three of the marginal edges thereof, there is formed a verti- Other vertically and longitudinally extending ribs I3 are formed in a spaced apart relation on the upper surface of the base member 30.

An under-sheet 34 of like material andV configuration has formed therein several. spaced rows of concavities or recesses 35, which recesses are shaped to receive cylinders 36 of sponge. rubber or similar resilientV material. The edges4 of said under-sheet 3.4 are disposed in the said groove 32 and are sealed therein by means of a heating or similar process; and, when so sealed, itis seen that the said. cylinders 36 are interposed between the said base member 30 and the under-sheet 34. Also, as inthe above described embodiment, a drain hole 2,5 is proyided, but in the present arrangerrientv it comprises. axially aligned apertures4 in only the base member 3 0 and the under-sheet 34,. Water is.. prevented from seeping between the base and the undersheet by a rubber sleeve 26 which is secured in place during the. mentioned sealing` process.v

amount of protection. If a dish were dropped on the base 30 directly above a cylinder 36, said cylinder would absorb the shock. If, however, a dish is dropped on an area of the base 30 between cylinders 36, that area absorbs the. shock and conveys it to the adjacent cylinders 36 between which it is suspended. Therefore, it will be seen that although less sponge rubber is utilized in the present embodiment, it is'equally effective as the described secondA embodiment.

In all of its above embodiments the pad body I0 affords protection to the bottom of the sink I5 against the abrasives included in scouring powders. This is so since, when employed, said pad is'interposed between the sink bottom and the pots whichy are being scoured.' Also, the grease which normally would accumulate on the sink bottom does so on the pad body IIl",Y from which it is more readily removed.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the righti's reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
